Problems solved by technology

[0002] At present, most of the batteries on the market are designed to meet the parking time of the vehicle for one month, and the risk of battery power loss increases during overdue parking. Among them, the vehicle does not sleep due to vehicle uncertainties, and some electrical appliances are still working after the owner leaves. There is a risk of battery loss
In this way, the battery is prone to power loss, which makes it impossible to start the vehicle through the battery power supply. It needs to provide an external power supply to start the vehicle, which causes great inconvenience to customers and there is room for improvement.

Abstract

The invention discloses a power shortage prevention system for an electric vehicle and the vehicle, and the system comprises a storage battery which is connected with a low-voltage electric accessoryof the electric vehicle; a power battery which is connected with a driving motor of the electric vehicle, and the power battery is connected with the storage battery through a DCDC; an electric quantity sensor which is arranged on the storage battery and used for detecting the electric quantity of the storage battery; and a control structure which is connected with the electric quantity sensor andthe power battery, the control structure controls the power battery to charge the storage battery when the power supply gear is in the OFF gear and the electric quantity sensor feeds back a low electric quantity signal, and controls the power battery to stop charging the storage battery when the electric quantity sensor feeds back a high electric quantity signal. According to the power shortage prevention system for the electric vehicle, it can be guaranteed that the storage battery is always in a charging electric quantity state, so that the storage battery always has the capacity of starting the whole vehicle, and the risk of power shortage of the storage battery is reduced.

Description

technical field [0001] The present application relates to the technical field of vehicle manufacturing, and in particular to a power loss prevention system for electric vehicles and a vehicle with the power loss prevention system. Background technique [0002] At present, most of the batteries on the market are designed to meet the parking time of the vehicle for one month, and the risk of battery power loss increases during overdue parking. Among them, the vehicle does not sleep due to vehicle uncertainties, and some electrical appliances are still working after the owner leaves. There is a risk that the battery will run out of power. In this way, the battery is prone to power loss, which makes it impossible to start the vehicle through the battery power supply. It needs to provide an external power supply to start the vehicle, which causes great inconvenience to customers, and there is room for improvement. Contents of the invention [0003] This application aims to sol...
